Protective potency of oil-treated cell walls of various mycobacteria against airborne infection of mice with a few cells of Mycobacterium tuberculosis H37Rv was compared with that of viable BCG. Although less potent than BCG cell walls, the cell walls of atypical mycobacteria of Runyon's groups I to IV protected against challenge by aerosol to some degree. Protection afforded by cell walls of H...
A hydroponic experiment was carried out to compare root anatomy and hydraulic conductivity of four barley cultivars including Valfajr, Karoon, Afzal and Zarjo under salt stress conditions. The results showed that under salt stress, the minimum diameter of vessels was observed in the peripheral metaxylem of seminal roots of Valfajr cultivar and in adventitious roots; Karoon with 19±3 µm had maxi...
to investigate the root anatomy and hydraulic conductivity of wheat cultivars, including shiraz, bahar, pishtaz, sistan, and yavaros, a series of controlled environment (growth chamber) experiments were hydroponically conducted at university college of dublin (ucd), ireland in 2010. bahar, pishtaz and sistan cultivars were employed as tolerant to drought and shiraz and yavaros as sensitive. twe...
